SOLVED: How to fix a bluetooth mouse that keeps disconnecting in Windows 8 & 8.1
So many perfectly good Bluetooth mice are sent back to the manufacturer for randomly disconnecting, when in fact they are working 100% fine. Most of the time it’s not the mouse, but Windows 8 that’s causing the problem. Here’s how I fixed it:
Search for Device Manager – select Human Interface Devices:
Go to Bluetooth AVRCP Device – Properties – Power Management –
then deselect “Allow the computer to turn off this device to save power”
You might also need to do this for Bluetooth HID Device and Microsoft Hardware Bluetooth Device if you have a Microsoft mouse.
Voila! It should stay connected from now on. You might need to remember to manually switch off your mouse from now on to conserve batteries when you’re not using it.
